RIVET-SETTING IJIACHINE.

Application le'd J'une 16, 1921. Serial No. 477,967.

To aZZ 'whom t may concern:

Be it known that I, EDWIN B. S'rrMrsoN, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Rivet-Setting Machines, o-f which the following is a specifi* cation. y

This invention relates to machines for setting rivets or the like in `leather or other sheet material, such machines including, as usual, a hopper, and a raceway down which rivets are fed toy a cut-olf and transfer slide which delivers them one by one to a pocket or holder whence the individual rivet is driven through a sheet of leather or other material. In such machines the lower end of the raceway has generally been made by aflixing strips of steel to the outer face of a stationary part fast to or integral with the machine head, with a unitary nose-piece fast to the inner face of the stationary part, having a rivet-guiding groove non-alined with the main raceway, the nose-piece hav` ing another groove eXtendinghoriZonta-lly and intersecting the rivet-guiding groove, and a slide in the horizontal groove adapted to be moved into alinement with and to receive a single rivet from the raceway proper, and then to be moved into alinement with and transfer the rivet to the rivet-guiding groove ofthe nose, whence the rivet drops into the carrier, immediately below a driver or plunger.

It is an object of my invention to simplify and improve the structure of machines of the kind referred to by supporting the slide on the nose-piece and between the latter and the stationary member; by making the nosepiece that is attached to the stationary member in two parts, separately secured to the stationary member and withopposed faces grooved to receive and guide a rivet in its descent from the rivet-guiding groove of the slide to the carrier whence it is driven by the plunger; and by providingcooperating parts in the stationary member and in the slide whereby the slide is held in position and restrained to a limited reciprocatory movement, and whereby the endwise removal of the slide may be permitted without neces sitating the removal of any other parts or their fastening devices.

Other objects and aims ofthe invention, more or less broad than those stated above, together with the advantages inherent, will be in part obvious and in part specifically referred to in the course of the following description of `the elements, combinations, arrangements of parts, and applications of principles constituting the invention; and the scope of protection contemplated will appear from the claims.

In the accompanying drawings, which are to be taken as part of this specification, and in which I have shown merely a preferred form of embodiment of invention,

Figure 13 is an enlarged elevation, with parts broken away, showing the outer face of thelower end of member 16 and the relation thereto of detent 30, and slide 27.

. Referring to the numerals on the drawings, and first to Figures 1 and 2, numeral 14 indicates the machine head, in

which slides a driver 15, actuated by suitable connections which it is not necessary here to show. Another stationary part of the machine, in which the stationary raceway proper is formed, is indicated at 16, and at the upper. end thereof is a hopper 17 whence rivets or the like are discharged into the raceway.

The upper section of the raceway consists of strips 18 fastened by screws to the outer face of stationary member 16, while the lower part comprises two cooperating plate sections 19, each having an attaching portion 2() whereby it is secured to the inner face of stationary member 16, and a noseportion 21 which has a shelf 22 that lies beneath the lower end of stationary member 16. Plate sections 19 are fastened in position by screws with the opposing edges of their nose-portions spaced apart, and in these opposed edges are formed grooves 24 non-alined with main raceway 18, which together constitute a guideway for the head of a rivet, the shank of the rivet passing in the space between the edges. Because there are two plate-sections the machining 'of the grooves 24 is a very simple matter, and by regulating the spacing of the sections, rivets of different sizes or diameters of heads may be accommodated. It will be understood that the lower ends of grooves 24 open adjacent the lower end of driver 15, the rivets passing down the grooves and into pocket 25. In the lower end or face of stationary member 16 there is a seat 26 for a slide 27 having a rivet-guiding groove 28 eX- tending through it transversely of its length, the lower edge of the slide moving on the shelves 22 of the nose-pieces 21, and one longitudinal face of the slide projecting to the outside between the lower end of member 16 and the adjacent nose-pieces 21. Reciprocation of the slide (by means not shown) moves it in one direction to register its rivet-guiding groove 28 with thel main raceway 18 of stationary member 16, whereby a rivet may d-rop from the main raceway into the .'groove 28. This groove 28 is capacitated to take one rivet at a time., and movement ofthe slide in the opposite direction registers the groove 28 with the guideway formed by the grooves 24 of the sectional plates 19, so that the rivet passes down and into the carrier 25 which, in the operation of the machine,brings the rivet into contact with the sheet of material into which itis to be driven, whereupon downward movement of the driver forces the rivet into the sheet and sets it, the carrier opening in a familiar manner to release the rivet.

In order to hold the slide 27 against endwise withdrawal and to limitits reciprocatory movements in both directions vto those positions in which its rivet groove 28 registers with either the raceway 18 or the grooves 24, I prefer to employ an internally threaded tubular member 29 set in the stationary member 16 from the outer face thereof, having on one (the outer) end a detent finger that normally lies in a seat formed in the outer face of member 16, preventing rotation of tubular member 29, and has its lower end projecting into a cut-out portion 81 in the outwardly projecting longitudinal face of slide 27 (Figures 2, 5 and 18), a screw 82 enterinlg the threaded member 29 from the inner face of stationary member 16, this screw 82 having a flange 88 which is held in position against the inner face of member 16, while permitting of its rotation, by means of a. set screw 84 entering int-o the inner face of member 16, and bearing against ange 88. If screw 82 be turned the result will be to move detent 8O into or out of its seat in the outer face of member 16, and into and out of the cut-out 81. Vhen the detent is moved entirely out of the cut-out 81 the slide 27 may be withdrawn endwise, butk without necessitating the removal of any other parts or their fastenings.

Inasmuch as many changes could be made in the above construction, and many apparently widely different embodiments of my invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
